Visitors

addNodesVisitor

Adds nodes (accounts, instructions, defined types, errors, PDAs) to existing programs in the Codama AST.

import { addNodesVisitor } from "@macalinao/coda-visitors";
import { accountNode } from "codama";

const visitor = addNodesVisitor({
  myProgram: {
    accounts: [
      accountNode({
        name: "customAccount",
        // ... account configuration
      }),
    ],
    instructions: [
      // Add custom instructions
    ],
    definedTypes: [
      // Add custom types
    ],
    errors: [
      // Add custom errors
    ],
    pdas: [
      // Add custom PDAs
    ],
  },
});

Usage with Coda

This visitor is commonly used in coda.config.ts to extend IDL-generated programs:

import { defineConfig } from "@macalinao/coda";
import { addNodesVisitor } from "@macalinao/coda-visitors";

export default defineConfig({
  visitors: [
    addNodesVisitor({
      voterStakeRegistry: {
        accounts: [
          // Add custom accounts not in IDL
        ],
      },
    }),
  ],
});
